How do u draw or define that line?
Sometimes, its better not to know too much, the smartest wife is one who allows the husband to stray a little but there has to be a line that neither will cross. Once that line is crossed, it might change the world game. For all you know, some already made their man wear green helmet especially during NS days, now the wife does her part and wear it as well. :P
As you said, what goes around comes around, some women strayed more than men...
My wife has one PRC colleague, married somemore. 2 colleagues always discussing about who uses her when. Tue-Wed, Mr Operations Manager, Thu-Fri, Mr Shipping Manager. Mon - Shared day as either can go out with her. Even her favourite positions are discussed in the pantry.
One time i was fixing a pc under a table, there were 3 innocent looking ladies along with 2 "old hands", an ex air stewardess(discredit her ex line because she was really an airhead) and another HR manager.
Guess what they were talking about, on washing machine, vacuum cleaners, when one talked loudly about having 2 guys in one day, another boasted she had 3in, was so shocked that i hit my head against the table and quickly came out, made an excuse and walked quickly out of a room with red faced ladies.
